What's Wrong?

Using VS Code extension for Windows, many basic slash commands are missing. Missing commands include, but may not be limited to:
/bashes
/help
/doctor
/ide
/output-style (but /output-style:new IS present and functioning)

These commands are both missing from the interface, and do not function if entered (they are interpreted as queries).

The commands are present when running claude code from the terminal. They are missing only in the VS Code native extension.

These issues are new as of today's updates (30 sep 2025).

What Should Happen?

Slash commands as described in official documentation should be present and functioning
